Trying to make a variable with for loop

Question

Trying to pick up a movieClip  instance from my library and set it on stage and make it clickable, (dropdown/dropup) menu). 
Can anyone help with what I am doing wrong?
var MenuItem1:Array = new Array("text1", "text2", "text3","text4");
CreateM(MenuItem1.length);
function CreateM(Menu1:Number):void
for(var i:Number=0;i<MenuItem1.length; i++)
      var this["M1"+i]:TextField = new TextField();
      var this["M2"+i]:takki = new takki();
      this["M2"+i].y = this["M2"+i].y-(i*50)+(stage.stageHeight-this["M2"+i].height);
      this["M1"+i].text = MenuItem1[i];
      this["M1"+i].y = this["M1"+i].y-(i*20)+(stage.stageHeight-this["M1"+i].height);
      addChild(this["M2"+i]);
      addChild(this["M1"+i]);
      this["M2"+i].addEventListener(MouseEvent.MOUSE_OVER,clicking);
function clicking(event:MouseEvent):void
trace("I am clicking button"&&this["M2"]);

Try something like this:
var MenuItem1:Array = new Array("text1", "text2", "text3","text4");
CreateM(MenuItem1.length);
function CreateM(Menu1:Number):void
for(var i:Number=0;i<Menu1; i++) { 
    this["M1"+i] = new TextField();
    this["M2"+i] = new takki();
    this["M2"+i].y = this["M2"+i].y-(i*50)+(stage.stageHeight-this["M2"+i].height);
    this["M1"+i].text = MenuItem1[i];
    this["M1"+i].y = this["M1"+i].y-(i*20)+(stage.stageHeight-this["M1"+i].height);
    addChild(this["M2"+i]);
    addChild(this["M1"+i]);
    this["M2"+i].addEventListener(MouseEvent.CLICK,clicking);
function clicking(event:MouseEvent):void{
trace("I am clicking button" && event.target.name);
Be aware, that you have to work with the positioning, and that the TextFields are overlapping the takkis, so that the clicking is only possible in a minor fraction of the takkis.
